Isospin Splittings of Baryons
K. Varga, M. Genovese, J. -M. Richard +1
We discuss the isospin-breaking mass differences among baryons, with particular attention in the charm sector to the , , and splittings…
Non-spectator contributions to B->X_s eta'
M. R. Ahmady, E. Kou, A. Sugamoto
We propose a nonspectator mechanism in which eta' is produced by two gluon fusion as the underlying process to explain the inclusive B-> X_s eta' as well as the exclusive B -> K^(*…
Renormalization of the Twist-3 Flavor Singlet Operators in a Covariant Gauge
Jiro Kodaira, Takashi Nasuno, Hiroshi Tochimura +2
We investigate the nucleon's transverse spin-dependent structure function g_2(x, Q^2) in the framework of the operator product expansion and the renormalization group. We construct…
Non-spectator contribution: A mechanism for inclusive B-> X_s eta' and exclusive B-> K(*) eta' decays
M. R. Ahmady, E. Kou, A. Sugamoto
We propose a mechanism which can explain the large BR(B-> X_s eta')~ 10^(-3) observed by CLEO. In this mechanism, eta' is produced by the fusion of two gluons, one from QCD penguin…
Chiral-odd transversity spin structure function of the nucleon in a constituent quark model
K. Suzuki, T. Shigetani
We study the chiral-odd transversity spin-dependent quark distribution function of the nucleon in a constituent quark model. The twist-2 structure functions, , $g…
Intermediate psuedoscalar resonance contributions to B->X_s photon photon
Mohammad R. Ahamdy, Emi Kou, Akio Sugamoto
We calculate the decay rate B-> X_s photon photon via intermediate psuedoscalar charmonium eta_c. This process is thought to be the main long-distance contribution which dominates…
